A formal defect investigation into Tesla’s Autopilot driver-assistance system was launched last month by the National Highway Transportation Safety Administration after almost a dozen collisions at crash scenes involving first-responder vehicles.
According to a report by TopAuto, the lithium-ion batteries that power Tesla models and other EVs are highly flammable and difficult to extinguish. "Once damaged, they can reignite hours or days after being doused, the safety board has warned.
"In January, the NTSB issued a special report about the dangers of battery fires from electric cars, saying manufacturers have left emergency responders vulnerable to battery blazes.
"The NTSB is also investigating a fatal crash in Texas involving a Model S sedan that hit a tree and caught on fire, killing both occupants in April," the publication's report states.
